the president then made an urgent plea to congress today and we do have it all covered for you tonight, beginning with the horror inside that supermarket. and abc's chief national correspondent matt gutman leading us off from the scene tonight. >> reporter: tonight, eyewitnesses describe how an ordinary trip to the supermarket turned into an afternoon of terror. one that left ten dead and the city of boulder reeling. dean schiller came to shop for groceries. instead he found this. >> someone's down, right here. something just happened here, guys. look, there's people lying in the [ bleep ] street, guys. he went in the store. >> one down right there. >> oh, my god. guys, we got people down inside king soopers. holy [ bleep ]. there's a shooter! active shooter, get away! >> reporter: ryan borowksi came for soda and a bag of chips. >> first shot, i thought it was an accident. i thought somebody had dropped something. second shot, i questioned. third shot, i knew it was gunfire. >> reporter: ryan tells me a woman came running toward him, a terrified look on her face.

then he started running, too. >> after i was running, i definitely heard more shots. kind of like, pop, pop, pop, pop, pop, pop. >> reporter: king soopers was also a covid vaccination site and steven mchugh's son-in-law paul was there to get one. >> paul was in line to go get a covid shot. third person in line and that's when at least one shooter came in and killed the woman at the front of the line, in front of him. >> we got people down on the ground. >> reporter: paul and his two young daughters sprinting for cover. >> they ran upstairs to hide. they hid in a coat closet, standing up for 45 minutes. extraordinarily terrifying. of course, the little one saying, "yeah, the coats weren't long enough to hide our feet," as they were standing behind the coats in the closet. >> reporter: sarah moonshadow was there with her 21-year-old son. >> i just started counting in between shots and listening to

see what direction he was heading in. i looked at my son and i told him, we only have three seconds, like, we have to move now. if we don't, we're not going to have another opportunity. >> reporter: sarah didn't see the gunman, but store employees described him to police as relentless, methodically going through the store and parking lot, where he shot an elderly man and then stood over him and shot him multiple additional times. >> once we got outside, i noticed that there were people laying in the street and they weren't moving and instantly, i started running for them and my son grabbed me and said, no, we can't do anything, they're out in the open. so we ran. >> reporter: by then, police were on the way. >> looks like we have an active shooter. it's a white male, middle aged, dark hair, beard, black vest, short sleeved shirt. >> the first responding officer talley, that showed up, i was going to try to flag him down

and my son was too afraid to let me go. >> reporter: you think you saw him running -- >> no, i know i saw him. he was coming down the street and turning into the parking lot. >> reporter: officer eric talley, an 11-year veteran of the force and father of seven, was the first one there. he was shot in the head and he died at the scene. >> officer down inside the building. >> eric talley died heroically. he died charging into the line of fire to save people who were simply trying to live their lives and go food shopping. >> reporter: his father said, "he was looking for a job to keep himself off the front lines. he didn't want to put his family through something like this." his sister kirstin tweeting this picture, saying, "i cannot explain how beautiful he was and what a devastating loss this is to so many. fly high, my sweet brother." so many lives cut short. the victims ranging in age from 20 to 65. 25-year-old rikki olds was a manager at the supermarket, she'd been there six years.

her uncle robert calling her the light of the room. jody waters was 65. she had two daughters, a grandchild and dreams of opening her own boutique. denny stong also worked at the grocery store. and there was suzanne fountain. friends say she loved the theater. >> our hearts go out to all the victims killed during this senseless act of violence. >> reporter: police say the shooter is 21-year-old ahmad alissa, an american citizen, who came here from syria as a 3-year-old. they say he'd been wearing a green tactical vest and carrying an ar-15 style rifle and a semiautomatic handgun. >> come out with your hands up unarmed. >> reporter: they say there was a gunfight. alissa was shot in the leg and then he surrendered. police walking him out of the supermarket into an ambulance. the rampage finally over. today, president biden expressing anguish at another mass shooting on the heels of last week's shooting spree in atlanta, which left eight dead. >> while the flag was still flying half staff for the tragedy, another american city has been scarred by gun violence

and the resulting trauma. and to state -- i even hate to say it, because we're saying it so often, my heart goes out. >> reporter: the president paying tribute to officer talley. >> every time an officer walks out of his or her home and pins that badge on, the family member that they just said good-bye to wonders whether they'll -- subconsciously -- will they get that call, the call that his wife got. >> reporter: tonight, officer talley's patrol car draped in flowers, a memorial to his sacrifice. >> that image of the patrol car so moving tonight. let's get right to matt gutman from boulder, and matt, police, of course, still searching for a motive. >> reporter: and it's an intense search, david. police and the fbi on the case. no word on motive yet. now, the suspect did surrender to police, but he refused to speak with them. he did, however, ask to speak with his mother. now, we've been watching investigators coming in and out of that supermarket. the police chief here says it will take at least five days to

process the scene. prosecutors say it will take at least a year to complete their investigation. of course, the suspect faces ten counts of first degree murder. david? >> all right, matt gutman leading us off tonight. matt, thank you. and matt, as you know, we followed this on the air all day today, and there was a moment when the boulder police chief maris herold grew visibly moved as she revealed she lived just three blocks from that store. and what she revealed about the officer and his seven children, all of them in her office just two weeks ago for an award. >> it's hard, it's challenging. i live three blocks up the street from that store. you're worried about your neighbors, you're worried about your partner, you're worried about everything when you get that call. and so, yeah, i feel numb. and it's heartbreaking. it's heartbreaking to talk to victims, their families. you know, it's tragic.

this officer had seven children. ages 5 to 18. i just had that officer's whole family in my office two weeks ago to give him an award. and so it is personal, this is my community, i live here. i can tell you that he's a very kind man. and he didn't have to go into policing. he had a profession before this, but he felt a higher calling. and he loved this community and he's everything that policing deserves and needs. he cared about this community. he cared about boulder police department. he cared about his family. and he was willing to die to protect others. >> that police chief not only working this case, but trying to help console her community. and tonight, we do have a clearer picture now of the

suspect emerging. what we've now learned about him and what court documents reveal about his earlier run-in with the law. and what he was allegedly doing just days ago. here's our chief justice correspondent pierre thomas tonight. >> reporter: tonight, police uncovering potentially ominous missed signals as they investigate accused mass murderer ahmad alissa. according to newly released charges, a female family member told police alissa was "playing" with a "machine gun" about two days ago at his residence. family members were angry that alissa was openly handling the weapon in the home and took it away from him before it eventually returned. another potential chilling indicator of what was coming -- alissa, last tuesday, bought a ruger ar-556. a pistol that looks remarkably like a small assault rifle which can accommodate a 30-round clip. police say alissa did not have a lengthy record, but investigators did point out that he was convicted in 2018 for misdemeanor assault on a high school student. accused of repeatedly punching

that student. other classmates telling "the denver post" that while alissa was often pleasant, he was quick to anger and once threatened to kill his peers. but why alissa, only 21 years old, of neighboring arvada, colorado, may have unraveled and allegedly exploded into mass violence still unclear. >> it would be premature for us to draw any conclusions at this point in time. >> reporter: authorities are searching through social media posts and assessing whether some are authentic, including one posting on a facebook page where someone identified as alissa claims he was mistreated because he was muslim and complained that he was being hacked. law enforcement sources telling abc news they are investigating whether alissa suffered from mental health issues. his brother telling "the daily beast" he believes alissa was paranoid. >> and pierre thomas, president biden briefed on the investigation today, he said, but also saying he would not speculate on a motive. and i know, pierre, you've also learned tonight that in boulder, the ban on assault weapons enacted by that city several

years ago was actually overturned just weeks ago? >> reporter: david, the boulder city council banned assault weapons in 2018, but the ban was recently lifted after a judge ruled that state and federal law supercede the local law. the suspect bought that assault-style pistol a week ago today, but we don't yet know if it was used in the shooting. david? >> all right, pierre thomas with us tonight, as well. pierre, thank you. tonight, president biden is now calling on the house and the senate to act, and here's what he said from the white house today. >> i don't need to wait another minute, let alone an hour, to take common sense steps that will save the lives in the future and to urge my colleagues in the house and senate to act. >> the president asking for a ban on high capacity magazines, a ban on all assault weapons and that he wants senators to vote for two bills that passed in the house already that would close background check loopholes. so, let's get to rachel scott at the white house tonight. rachel, what's the bottom line

here? will there be votes, will there be movement on this? >> reporter: david, the reality here, this faces a massive uphill challenge in the senate. majority leader chuck schumer says he's committed to bringing both bills to the floor, but the bottom line here, democrats just don't have the votes to get it passed. they need the support of at least ten republicans. so, tonight, the white house is eyeing ways to be able to address gun violence through executive action, but any major reform is going to require the help of congress, david. >> all right, rachel scott, pierre thomas, matt gutman, we thank you all tonight. and of course, we'll stay on this. rachel, thank you. we're going to move now to the other news this tuesday night. the troubling new headline involving that potential new vaccine from astrazeneca, just hours after releasing promising results of its u.s. vaccine trial. the national institutes of health questioning the findings, saying the company, quote, may have included outdated information from that trial which may have provided an incomplete view of the efficacy data. the company now promising to turn over newer data within 48 hours.

and here's what dr. anthony fauci told "gma." >> this is really what you call an unforced error, because the fact is, this is very likely a very good vaccine and this kind of thing does do nothing but really cast some doubt about the vaccines and maybe contribute to the hesitancy. >> and tonight, the numbers on the vaccines. 83,705,000 people have received at least one dose, that's more than 32% of adults. and again, astrazeneca promising that new data within days. we turn next here tonight to the new video from inside one of the crowded facilities on the southern border housing thousands of minors coming to the u.s. alone. this video tonight shot by customs and border protection last week, first obtained by abc news, showing children sleeping on floors. abc's cecilia vega tonight on patrol with border authorities and the phone numbers written on the children's clothing. >> reporter: tonight, on the southern border, authorities in a race to keep up. on patrol with deputies from hidalgo county, texas, we spot a group of families who just crossed the rio grande.

in this group, 15-year-old jeffrey, traveling alone from honduras. he's very, very tired, he says. and what's next now that he's arrived? he tells me, only god knows. just up the road, an even bigger group. in it, 9-year-old justin and 10-year-old joseph. both traveling alone, walking for more than a month. the group has taken them in, strangers promising to keep them safe. the boys show me phone numbers of family members in the u.s. they soon hope to find. justin takes off his backpack to show me this hat. this is his grandfather's phone number. joseph's aunt's written right here. this is his aunt's phone number. the children likely to end up in a facility like this. they still won't allow journalists inside. but customs and border patrol releasing this video shot last week. only 250 people are supposed to be held here. instead, there are close to

4,000, side by side, huddled under foil blankets, toddlers in a playpen being watched by a caretaker. tonight, the white house under fire from all sides, accused of not having a plan in place to handle the surge after it overturned many of president trump's hardline immigration policies. democratic congressman henry cuellar of texas calling the situation at the border something the white house won't -- a humanitarian crisis. >> the administration has all the good intentions. they want to treat the kids in a humane way. but in trying to do this, their good intentions are being overwhelmed by numbers. >> reporter: the children just keep coming. those little boys we met, justin and joseph, justin tucking that hat with his grandfather's phone number away for safekeeping. "are you scared," i ask. "yes," they tell me. they are scared. and we spoke to justin's grandfather, we called him, his number was on that hat, he says justin's mother sent him north because she understood that authorities here were allowing kids who traveled alone to stay

if they came into contact with the border patrol. david, the white house says sending those kids back alone across the border as trump did is inhumane. we're talking about desperate families here. >> all right, we know you're going to say on this, cecilia. our thanks to you again tonight. when we come back, outside new york city, the deadly fire at an assisted living facility. a firefighter also missing tonight. we're also tracking two major storms on the move. we'll be right back. struggling to manage my type 2 diabetes was knocking me out of my zone, but lowering my a1c with once-weekly ozempic®
